Abstract

Every industry, organization or individual needs to be minimize their expenditure, time
and fatigue and maximize their profit in supply chain. These goals can be achieved through
automation by using Radio Frequency Identification (RFID) and Zigbee wireless communication
technologies, which is easily available in the market. Basically RFID technology is used for
automatically tracking, locating or identifying the entities. It can easily integrate with low cost low
power consumption Xbee (Zigbee) device, which is used to increase the communication range by
large number of node deployment. RFID-Xbee network integrates with Laboratory Virtual
Instrument Engineering Workbench (LabVIEW) Graphical User Interface (GUI), which gives real
time information of supply chain at single control panel. The integrated communication model
proves the near field inductive coupling and can be used in supermarket for item pricing, office
automation, security system, and car parking. This system confirms the concept of real-time locating
system (RTLS) in an indoor environment. The impact of RFID and Xbee network communication
model enhance the read range of RFID reader, so that out of range items can be tracked easily
without additional RFID readers. The benefit of this system is to maximize profit, reduce human
intervention and minimize waste.
